It's not entirely clear what you're trying to ask.

  • There can only be one kind of molecule in a compound (otherwise it's a mixture).
  • There can be any number of (identical) molecules in a compound; it just depends on how much of the compound there is.

What is the difference between formula mass and the molecular mass of a compound?

1 mol is equal to 6.02214179(30)×1023 molecules of the substance. The molecular weight is how much grams these molecules (6.02214179(30)×1023) weigh. Meaning g/mol.


A compound formed of 0.059 mol hydrogenand 0.94 mol oxyegn has a molecular mass of 34.0what is the molecular formula of this compound?

The molar ratio of hydrogen to oxygen in the compound is 1:1. This means the compound is water (H2O), which has a molecular mass of 18.0 g/mol, not 34.0 g/mol. The given molecular mass of 34.0 g/mol does not match the properties of water.


How many molecules of sulfur tetrafluoride are present in 2.13 moles of this compound?

There are 1.28x10^24 molecules of SF4. 2.13 mol * 6.022x10^23 molecules/mol = 1.28x10^24 molecules.


The empirical formula of a compound is CH2O The molar mass of the compound is 180 g What is the molecular formula for this compound?

The empirical formula CH2O has a molar mass of 30 g/mol (12 g/mol for C + 2 g/mol for H + 16 g/mol for O). To find the molecular formula, which is a multiple of the empirical formula, you divide the molar mass given (180 g/mol) by the empirical formula mass (30 g/mol), giving you 6. Therefore, the molecular formula for the compound is (CH2O)6, which simplifies to C6H12O6, the molecular formula for glucose.


A compound formed of 0.059 mol hydrogen and 0.94 mol oxygen has a molecular mass of 34.0 gmole What is the molecular formula of this compound?

The molar ratio of hydrogen to oxygen in the compound is 2:1. To find the empirical formula, divide the moles of each element by the smallest number of moles, which is 0.059 mol for hydrogen. This gives a ratio of 1:0.5 for hydrogen and oxygen, which simplifies to the empirical formula H2O. To find the molecular formula, calculate the molecular mass of H2O (18 g/mol) and divide the given molecular mass (34 g/mol) by the empirical formula mass to get the multiplier of 2. So, the molecular formula of the compound is H2O2.
